RADIATOR.

To all whom t ma? concern.' v

Be it known that I, Josnrrr T. SCHLACKS, a citizen of the United States, residing at Detroit, in the eountyo Wayne and State of Michigan, have invented certain new and useful Improvements in Radiators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make, and use the Same.

Generally stated, my invention is directed to the improvement of4 radiators, but more partieularly,`has for its object the improvement of that type of radiator extensively used in connection with automobiles 'and known as the cellular type of radiator. It

1s the common practice to .make these cellular radiators of thin sheets of brass or copper, bent each to form a multiplicityy of alternated relatively narrow and wide angular plaits or corrugations. These plaits, when assembled in the completed radiator, give theV same a rectangular cellular appearance and form longitudinal air passages and intervening vertical water conduits having laterally projecting water spaces.

y improved radiator, in its preferred form, is illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views.

Referring to the drawings: Figure 1 is a perspective View showing the complete radiator core orcellular body; Fig. 2 is a fragmentary horizontal section taken approximately on the line .mL-:o2 on Fig. l; Figs.` 3 and 4 are views in end elevation showing two of the so-called units of the radiator, portions of the unit shown in Fig. 3 being broken away; Fig. 5 is a perspective of the unit shown in Fig. 4 with one plaited side thereof broken away; and Fig. 6 is a detail v'in horizontal section showing the radiator core unit illustrated in Fig. --L on an exaggerated scale. and particularly illustrating the manner in which the ends of the plaited sheets of the`units are preferably united, some parts being broken away. i

This improved radiator is made up of a of so-called units, to-wit, of an appropriate number of units such as shown number of units',

The radiatorv u'nit constructed as shown in Figqi, has horizontal upper and lower walls l thus formed, whereas vthe ra` diator unit such as shown in Fig. 8 has oblique top walls l formed in themanner indicated. stated that, advisably,these corrugated sheets of the horizont-ally alined plaits 2, are inter- L posed flat and very rigid metal parting and reinforcing strips -l that extend from the bottom to the top walls 1n or 1, asthe case may be, of the radiator unit in which they are applied. These combined parting and y radiator unit, `arev made' a single or continuous strip of sheet are made in long strips orl ribbons and are cut into proper lengths, and

eo f

and bottom or corner forming reinforcing strips space apart the adjacent j portions of the horizontally alined plaits 2 and form air passages 5 that connect the horizontal air passages 3, so that air can circulate vertically in,l asl well as horizontally through `the radiator unit. Otherwise stated, the air passages 5 afford vertical communicationbetween the horizontal air passages 3 ofthe radiator. The parting strips 4, for an important purpose hereinafter to be fullyvvstated, proJect prefioo adjacent and connected sheets will be spaced apart andwill form water tubes having vertical water conduits G with horizontally alined laterally otset water spaces formed within the oppositely projecting plaits Q ot' y theadjacent units. The radiator elements,

when properly assembled, make a cellular radiator core that is octagonal. Otherwise stated, they make a core that would otherwise be rectangular but has beveled corners. Hitherto, it has been customary in making cellular radiators, to first make the core rectangular and then to saw oil the corners. '.lhat operation requires subsequent resoldering of all of the numerous joints cut through in sawing olic the corners of the core, and this, obviously, is a slow and expensive operation, which, when completed, does not give a finished or satisfactory job. My improved manner of forming the beveled corner forming ends on certain of the outside units of the radiator core gives a finished and completely satisfactory job at a miniw mum of cost. The units ofthe radiator, when properly assembled in suitable form, have their joints closed at the front and rear edges 2b of the corrugations 2, and parting strips 4l are 'rigidly united to the ends of nthe said corrugations 2, by subjecting the same to a solder bath. The parting and reinforcing strips e perform several important functions, to-Wit, they very greatly reinforce the radiator coreA 1When used in connection with the plaited metal sheets, they serve to space the plaits thereof, to afford vertical communication between the horirental air passages; and when projected at their edges beyond the face of the radiator,

or beyond the vertical. edges of the relatiwelyY thin and pliable metal sheets, they allor-d a guard adapted to receive impacts and to protect the edges of the plaited, or otherwise formed relatively soit sheets, from being' distorted or bent out of shape. Y of this character when applied in automoloiles, are, as is well known, exposed at the front ot the machine where they receive the brunt of almost all head-end collisions or eompjactgand as the pliable sheets of the core are very easily distorted, these radiators ,are very frequently distorted and the radieters 'seriously damaged even by compara- Radiators hacerte tively iight impacts. In fact, a very large amount of repair work on these cellular radiators is made necessary from these causes. rlhe parting and reinforcing strips are, oi course, of much thicker metal than the plaited sheets of the radiator c' c, and when the said strips are made of steel. they make the radiator core very rigid. Ot course, the projection of the parting` strips at the front face Vof the radiator corel is more important than at the rear, but there is an advantage in projecting both in front and at the rear, vbecause the irail soit metal sheets of the core -are very liable to be damaged, by breaking` ot the frame or even by workmen making repairs or working around the radiator.

TheV complex horizontal and vertical circulation of air between the elements of the radiator, and the large amount of radiating: surface exposed to the air thus circulated, resulting` from the formation of the water conducting tubes, gives a radiator an eX- ceedingly high heat radiating;` and cooling etlicieucy. It will, of course, be understood that in practice, `the upper extremities ot' the water conduits or conducting tubes will be in communication 'with an upper water head or tank, whereas. the lower extremities of said conduits or'ltubcs will bein communication with a lower water head or tank,

which water heads or tanks are connected to the water jacket of the/explosive engine of the automobile, by ineans ot' suitable water circulatingtubes.

The improved radiator, while particularly designed and especially adapted for use in connection with automobiles, is, as will be understood, capable of general use wherever a radiator of this general character may be found serviceable.
